Specification of Letters Patent.

Patented May 28, 1918.

Application led November 8, 1916. Serial No. 130,256.

To all whom it may concern:

Be it known that I, JOHN YOUNG, a citizen of the United States, residing at Chillicothe, in the county of Ross and State of Ohio, have invented certain new and useful Improvements in Presses, of which the following is a specication.

This invention relates to presses, particularly baling presses, although the invention is not specifically limited to the same. Primarily, my invention relates to means whereby a press of this type may be readily transported from place to place by mechanism carried by itself. It is oftentimes desirable to move a press from one location to another and inasmuch as these presses are usually of considerable weight, it has been a source of considerable inconvenience to place them upon a truck or otherwise transport them.

Another object of my invention resides in means for operating the roller supporting structure to transfer the weight of the press from the main framework to the rollers by the operation of the plunger operating means of the press itself. This arrangement does away with additional mechanism used solely for the purpose of transferring the weight of the press from the main framey work to the rollers.

Still a further object of my invention resides in a structure for transferring the weight of the press from its main framework to the roller structure, which may be y u operated either while moving the plunger up and down or by leaving the plunger stationary, but at the same time utilizing lthe plunger operating means for accomplishing this end. This arrangement may be had by the provision of a peculiar type of clutch or other connecting mechanism between the plunger and its operating means as will be described.

, The preferred, embodiment of my invention is shown in the accompanying sheets of drawings, in which similar characters of reference designate corresponding parts, and in which:

Figure 1 is a central vertical ysection taken through a press and showing my invention applied thereto,

Fig. 2 is a horizontalI section taken on line 2 2 of Fig. 1,

F ig. 3 is a vertical section taken on line 3-3 of Fig. 1,

Fig. 4 is a view in perspective of a gear wheel forming a portion ofthe operating mechanism as used by me, and,

Fig. 5 is a fragmentary view in perspective showing the roller structure and a portion of its operating mechanism.

In these drawings, I have not attempted to show the completed press structure, but have confined myself to the showing of a general frame work which comprises upstanding end channels 1, transverse upper channels 2 and transverse lower channel members 3. End base members 4 are provided in order to give stability to the structure when itis resting upon the press framework'and also, the base channels 2 have been provided with a bottom plate 5 between which and the plunger' plate 6, the material operated upon is adapted to be compressed. This plunger plate is connected to a pair of rack members 7 designed to mesh with pin* ions 8 carried upon the shaft 9, which shaft is suitably journaled as is shown at 10 at its opposite ends i-n the main framework.

This shaft 9 forms a portion ofthe plunger operating means and its projecting endv 11 is provided with an internally and eXternally toothed gear 12. This gear is rotatablyV mounted upon the shaft, but is keyed thereto by means of the hand wheel 13,which latter is itself slidably keyed to the shaft 9, as is shown, and whose hub 14 is provided with a series of teeth 15 to mesh with the internal teeth of the gear 12. Thus, when the hand wheel 13 isin the position shown in full lines in Fig. 1, the gear 12 is operatively keyed to the shaft 9, but when this hand wheel is in the position shown in dotted outline in Fig. l; this gear is rotatably mounted on the shaft 9. The gear 12 also meshes with a pinion 12a, which rigidly carries a worm wheel 16 to one side, the combined spur and worm gear being rotatably vmounted on the stub shaft shown at 17. A

worin 18 mounted on the shaft 19 meshes with a worm wheel 16, as is shown and this worm is rigidly keyed to the shaft 19 so that operation of the hand wheel 2O causes the entire train of gearing to be set in operation. Thus, by rotating the hand wheel 20, the worm 18 is rotated to correspondingly rotate the worm wheel 16 and spur pinion 12.

, This latter meshes with the spur gear 12 and,

when the hand wheel 13 is in the position These rollers are mounted on shafts 22,. which v latter are suitably supported in a yokememshown in full lines in Fig. 1, the shaft .9 is also rotated to correspondingly movel .the plunger 6.

When the press is in use, its framework rests directly upon the floor, but whenit is.

v desired Ito v.transport lthe" same, the vIi'ollers shown at 21 are moyed tothe position shown in dotted outline inFig- 1, whereby the entire press will be supported upon. them .and'umay thereby` be readily transported.

' `berdesignated by thereferencenumeral 23.

This yoke memberispivotally mounted at itstwo. ends, as is shown at 211, to the mam framework, but its opposite end is operativelyconnected, as tis shown at 25, to a" strut -ymember-26. Y

The upper end of this vstrut is `slidably mounted in a casting shown at 27, which casting forms a portion ofone of the bearings'lO Iand also a portion ofthe kmeans for supportingthe stub shaft 17 To ,thenpper end of the strut 26 there is pivotally' attached at 28 a catch member of the nature 'shown at 29. This vcatch, member y, comprises abodyportion with an upstanding lugQQ at one end, which forms the means of pivotal connection with the strut andits lother end is provided with a shoey projection 31, the entire catch member resting upon the horizontal leg 32 of the shelf member shown at 23k when it is inthe position shown in Figs. 1 and 3. kReferring'to Fig, 4 particularly, it-will'be noted'vthat the gear wheel 12 is provided -with aplurality of laterally pro- Ijectingpins 34, whichpins lare arranged to cooperate -with ,theshoeproj ection 31. Thus, -pwhen the catch member 29 is moved from the positionshown in full linesinFig; 3, to Ythe :position-shown in dotted lines `in this figure, l thejslioeprojection"31 will lie` in the rotativemoveme'nt of the pins 84. y As soon as 'one of these pins engage the shoe, :they strut-26will be forced downwardly to cor- .respondinglyimove the right hand .end of thefyoke member 23. Suflicientmovement y path of of this y:yoke member will bring the rollers 21iinto engagement with the floor, and in this ymanner 'the weightfof the entire press is transferred from the framework to the rollers. A Y f "These rollers 21I may be moved toI their supporting position simultaneously withthe movementofthe plunger 6, byl'eavingfthc hand wheel` 13 yin the position shown in full lines in Fig 1, orv this hand wheel may be i ywithdrawn to assume thevposition shown in .dotted lines linfFig, 1' ,and by operating the f hand avheel20, thepplungei- 'G will remain in '-its'fpos'ition,A While the rollers 21 -are being ,movedftol afposition of support forthe en- .;-ti'eistriwturea N0 mattersivhether. thaplun- :.L...V.,.,. .fil-.l w/,f ,LU ,v v H. ger fis being moved or not, the drive connection between the worm wheel 16 and the worm 18 causes a lock to prevent the rollers fromreturningtto a position of non-support.

From the -`foregoing description, it will be apparent that I have provided a type of press which, under normal conditions, has

a vsupport upon the floor by imeans of its framework. However, should it be desired to transport-"the same, the rollers 21 may be readily moved to ka supporting position `t0 eifect such transportation.
